# <default>:   	 make hugs
# hugs:    	 make minimal working system
# runhugs:   make standalone evaluator
# clean:       	 delete files not required in running system
# distclean:     delete files that can be regenerated using C compiler
# veryclean:     delete all machine generated files 
#                  (you need perl, bison/yacc, etc to rebuild these files)
# check:	 run regression tests
# TAGS:          build emacs TAGS table

# This rule goes first to make it the default choice
